District Vs At Large Elections

District Elections

Before 2022, all registered voters in the City voted for all five members of the City Council. Beginning in 2022, residents voted for candidates running in their specific district. Learn more about San Mateo's transition to District Elections.

At-Large Elections

Several cities, school districts, and special districts in the County still use at-large elections. Other places this type of election is seen include:

  • State offices: Governor, Lieutenant Governor, Secretary of State, State School Superintendent, State Attorney General, etc. 
  • U.S. Senator
  • Larger cities will have district elected Councilmembers with an at-large Mayor (Ex: San Francisco, Oakland, and Los Angeles)
